# Service bulletin SSM 50258

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

- Type: Service bulletin
- NHTSA id: 10203850
- Published by NHTSA: 2021\-12\-07
- Manufacturer's number: SSM 50258
- Manufacturer's date: 2021\-11\-04
- NHTSA component: UNKNOWN OR OTHER; COMMUNICATION:MANUFACTURER TELEMATICS

## NHTSA's summary

Various 2012\-2015 vehicles equipped with a 3G modem may experience a lack of 3G modem performance. This may be due to the 3G cellular service functionality being decommissioned starting August 2021 and through March 2022. As the 3G cellular service is decommissioned, vehicles equipped with the 3G telematics control unit \(TCU\) will lose MyFord Mobile and MyLincoln Mobile app functionality/connectivity. Repair or Replacement of the TCU should no longer be performed using existing service stock. Replacement of the 3G TCU for this concern will result in programming concerns and repairs should not be performed.
